ASME B16.5 class 150 flange is one of the different classes ranging from 150 through 1500 in the B16.5 standard. R.C. Metal Corporation is a leading supplier of different ANSI B16.5 150# Flange Dimensions and different types of them. There are different pressure numbers and classes that show the pressure capacities, wall thicknesses and diameters of the 150 lb flange pressure rating. There are different faces to the Class 150 Pipe Flanges such as the flat face, raised face and the ring type joint flanges. The flanges range between ¼ inches to 24 inches in nominal bore size under the B16.5 standard. The Flange 150# is one of the lower classes and can be used for low pressure applications.
The applications include domestic water line, sea water desalination plants and petrochemical applications as well. The Slip On Flanges Class 150 can be made from different materials such as the stainless steel, carbon steel and high alloys. The difference in the material brings different mechanical properties such as the tensile strength. The Class 150 Weld Neck Material can range in strength from 205MPa minimum yield strength for 304, 316 and 310 types of steel to 930MPa in duplex stainless steels. The Stainless Steel Class 150 Flanges are the most used ones with 304 grade being the most used grade because of the low cost and high strength.
The corrosion resistance of the Class 150 Carbon Steel Flanges depends on the material as well. Some applications such as chemical applications, pharmaceuticals, specialty chemicals and food processing need high corrosion resistant MS Flange class 150. The mild steel and carbon steel flanges are used in different wear and tear prone applications. The carbon steel made Class 150 weld neck flange has high toughness and a welded neck for extra grip on connection. We manufacture all types such as the Class 150 Threaded Flanges, screwed flange and forged flange types. Please feel free to contact us for more information on the flanges and their prices.
